SNAP-HOOK.

SPECIFICATION forming part of Letters Patent No. 475,971, dated May 31,1892.

Application filed August 21. 1891. Serial No. 403.307. (No model.)

To all whom, it may concern:

Be it known that I, FRANK WHITE, a citizen of the United States,residing at Pomona, Los Angeles county, State of California, have invented an Improvement in Sn :1 p-llooks; and I hereby declare thefollowing to be a full, clear, and exact description of the same.

My invention relates to snap-hooks; and it consistsin thenovelconstruction of the parts hereinafter fully described, and specificallypointed out in the claims.

The object of my invention is to provide a strong, simple, neat,economical, and generally-eltective snap-hook.

Referring to the accompanying drawings for a more complete explanationof my invention, Figure 1 is a view showing the blank from which themain portions of my hook are formed. Fig. 2 is a view of the hookcomplete. Fig. 3 is a View of the blank from which the link connectionis formed. Fig. at is a view of the blank from which a ring connectionis formed. Fig. 5 is a view of a swivel-ring connection. Fig. 6 is aView of the base of the snap-hook, showing it adapted to receive a strapor rope directly. Fig. 7 is view of the blank from which the bolt I isformed. Fig. 8 is a view of the completed bolt. Fig. 9 is a modificationof thelower end or base of the snap-hook. Fig. 10 is a view showing thelink connection stationary.

The blank shown in Fig. l is made of a single piece of metal. preferablyof sheet-steel. \Vhen bent in thelongitudin al center, it forms asnap-hook, as shown in Fig. 2. The similar parts of these two figuresare easily recognizable, A being the part in the blank which forms thebarrel A of the hook, B forming the head, 0 the nose of the hook, theopening D the month, the slot E the guide for the thumbpieee of thebolt, the perforated ends F the ears for the attachment of the link orring, and the flange or lip G the abutment or base for the lower end ofthe spring 11, the upper end of which bears upon and controls the boltI, which is seated in the hollow or cavity of the barrel. This blank, itwill be seen, is a simple one, can be readily stamped out, and easilybent into form. Thus from a single piece of bendable metal are formedthe barrel, head, nose, mouth, boltguide, springbase, and link-ears of asnap-hook.

A point of advantage is to be observed in the manner of forming thenose, which, as will be seen from Fig. 2, is solid on its front from itspoint back to its bend. This gives it a good appearance and preventsanything from catching upon it. Similarlythe front of the barrel issolid and smooth. The flange or lip G forms the abutment for the base ofthe spring by simply bending it across the open lowerend of the hollowbody, as seen in Fig. 2.

In Fig. 3 is shown theblank from which the link connection of thesnap-hook is formed. This blank, which is also of sheet-steel, is to bebent in the transverse center. Then the shank or stem portion .T formsthe eye-piece J of Fig. 2, and the oblong slotted ends K form the oblonglink K of said Fig. 2. The link is fitted to the snap-hook by means of apivot bolt or pin L, which passes through the perforated ears of thehook and through the intervening eye-piece of the link. It a ring bedesired instead of an oblong link, such ring can be formed from themetal blank M (shown in Fig. 4) by bending it in the line of itstransverse center; or a swivel ring or link N may be used, as shown inFig. 5, by fitting it over the button-shaped shank of an eyepiece 0,formed from a suitable metal blank; or, as shown in Fig. 6, there may beno link or ring at all, but simply the bolt or pin L, adapted to receivethe eye-piece of a strap or rope or chain.

Fig. 7 shows the metal-blank from which the bolt I of the snap-hook isformed. The portion marked I of this blank is bent into substantiallycircular form inits longitudinal center to form the bolt-body, while theportion tis bent transversely upon itself to form the thumb-piece t',which projects from and slides in the slot E of the barrel of the hook.This bending of the blank of Fig. 7 results in the bolt shown in Fig. 8and also shown in position in Fig. 2.

Fig. 9 shows a modification of the lower end of the snap-hook. In thiscase the ears are brought close together and the ring or link is pivotedupon the projecting ends of the pin or bolt outside of the ears.Theabut- Inent lip 0r flange is substantially the same as before or maybe omitted. It the pivotal motion of the link of Fig. 2 be not desired,the ends of the ears may be flattened to allow ICO the link to restsolidly against them,as shown at P in Fig. 10.

It is plain that instead of the bolt I, formed from the blank of Fig. 7,a cast, malleable, or other form of bolt may be used in my snaphook, andalso that with my said hook I may use a cast, malleable, or other formof link or ring connection.

1 may briefly describe the advantages of my snap-hook to be increasedstrength, simplicity, lightness, neatness, and economy in manufacture,the facility with which any sand or dirt may escape from the tubularbolt 1, instead of being retained to impede the action of the spring,and the saving of wear on the leather or rope by means of the pivotallink or ring.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A blank for a snap-hook, formed of a single piece of bendable metalmade with a portion A to form the barrel of the hook, a portion B Withpart 0 to form the head and nose of the hook, said portion beingprovided with an opening D and a downwardly-extending slot E, which formthe mouth and the guide for the thumb-piece of the bolt, respectively,and the perforated portion F, forming the end ears of the hook,substantially as herein described.

2. A blank for a snap-hook, formed of a single piece of bendable metal,made with a portion A to form the barrel of the hook, a

portion 13 with part C to form the head and nose of the hook, saidportion being provided with an opening D and a downwardly-extending slotE, which form the mouth and the guide for the thumb-piece of the bolt,respectively, the perforated portion F, forming 'the end ears of thehook, and the flange or thumb-piece t' at right angles thereto.

4. A snap-hook consisting of a single piece or blank of metal bent uponitself to form the slotted barrel, head, nose, mouth, guide- ;slots,perforated end ears, and flange or lip forming an abutment, a slidingspring-coir trolled bolt of bendable metal, and a ring or linkattachment formed of a single blank of metal bent upon itself andadapted to be attached to the ears of the barrel, substantially asherein described.

In witness whereof I have hereunto set my hand.
